Abstract
It is a fact that excessive traffic of machines on natural sources and agricultural fields increases soil compaction. The study of soil compaction requires determination of the stress state of soil. A transducer was designed to measure normal pressure in six predetermined directions. The pressure transducer composed of six sensing units and a core. The Data Acquisition System used in this research consists of a data logger, a printer and a recorder. The data collected were used to determine shear stresses which in turn can be utilized for calculation of soil stress state. The change in soil density due to the excessive traffic can be calculated by these data.
